FAN & LIMIT LOCATION FOR HORIZONTAL UNITS WITH AIR CONDITIONING COIL:
The fan & limit control should be mounted between the H-coil cabinet and furnace. For distances from top of plenum
and furnace, see Fig. 7. IMPORTANT: Do not try to mount fan/limit in H-coil cabinet.
NOTE: The OL2, OC2 and OH2 only, come standard with an oil filter packaged with the furnace. This filter has the
capacity of filtering down to a 10 micron particle. This is to assure the small diameter burner nozzles in the low
heating capacity furnaces are installed with a fine filter to help prevent nozzle clogging.
